WHAT IS ECOFRIENDLY ENERGY?
Eco-friendly energy is energy that does not disrupt or disturb ecological processes or the earth’s biogeochemical cycle. Advances in civilizations have always been closely linked with availability and exploitation of energy, manufacturing and technology relied on dependable sources of energy and in the twentieth century world energy consumption had increased because of population increase. Fossil fuels are the most commonly used by industrialized nations (in fact the world at large) these are oil, coal and gas which supplies about 90% of the worlds commercially traded energy. Fossil fuels were formed hundreds of millions of years ago; they are an accumulation of energy rich organic molecules produced by organisms as a result if photosynthesis over millions of years, fossil fuels are like concentrated stored solar energy. because they are getting depleted and take along time to form they are known as finite or non-renewable resources of energy they also burn up to release excess carbon dioxide into the environment which depletes the ozone layer and in turn causes the earths global warming. On the other hand there are several renewable energy sources which replenish themselves or are continuously present as a feature of the earths ecosystem, hence the term eco friendly some forms of renewable energy are also referred to as perpetual energy, for example in plants photosynthesis converts light energy to chemical energy. Carbondioxide+water+sunlightenergy-----} biomass/chemical energy oxygen This energy is stored in organic molecules of the plant as wood, starch Oils or other compounds .which means any form of biomass energy /biofuels can be tracked back to the energy of the sun. Solar, geothermal, tidal and biomass energy are said to be renewable energy sources and eco-friendly because they’re continuously available in the ecosystem. Progress has been made in the use of renewable sources of energy, however technical, economic and cultural challenges must be addressed before renewable energy would meet a significant percentage of human’s energy demands and hereby curb the problems of climate change and increasing greenhouse emissions caused by burning up fossil fuels.
Biofuels, biomass, geothermal, hydro power, solar power, tidal power, wave power are all naturally replenished. In 2006about 18% of global final energy consumption came from renewables with 13% coming from traditional biomass, such as wood burning .hydro electricity was the next largest renewable source, providing 3%, followed by solar hot water heating, which contributed 1.3% .modern technologies, such as geothermal energy, wind power, solar power and ocean energy together provided some 0.8% of final energy consumption. Climate change concerns and coupled with high oil prices, peak oil and increasing government support are driving increasing renewable energy legislation, incentives and commercialization. European union leaders reached an agreement in principle in march2007 that 20 percent of there nations energy should be produced from renewable fuels by 2020 , as part of its drive to cut emissions of carbon dioxide , blamed in part of global warming. Investment capital flowing into renewable energy climbed from$80billion in 2005 to a record $100 billion in 2006.
In response to the G8’s call on the IEA for “guidance on how to achieve a clean ,clever and competitive energy future”, the IEA reported that the replacement of current technology with renewable energy could help reduce co2 emissions by 50% by 2050, which they claim is of crucial importance because current policies are not sustainable. Wind power is growing at the rate of 30% annually, with a worldwide...
